Kennel, google PREEMPT RT if you want to know what rt *is*. You'll find plenty of information on the subject. In short though, the RT kernel is a lower latency kernel. Meaning processes should "hog" CPU time less.
As far as the 4.x kernel in General, for the most part it is fine, but there are a few things that do not seem to work correctly. But that is why the kernel is testing. You test it for your purpose, and if something doesn't work you report it to Robert, and perhaps the issue then get fixed very quickly. I can tell you that at least for me the 4.x kernel is noticeably more responsive than older kernels.
